Driver model updates for the I2C core:
- Add new suspend(), resume(), and shutdown() methods. Use them in the
standard driver model style; document them.- Minor doc updates to highlight zero-initialized fields in drivers, and
the driver model accessors for "clientdata".If any i2c drivers were previously using the old suspend/resume calls
in "struct driver", they were getting warning messages ... and will
now no longer work. Other than that, this patch changes no behaviors;
and it lets I2C drivers use conventional PM and shutdown support.Signed-off-by: David Brownell

Remove a superfluous initialization from the vt8231 hwmon driver; the
i2c core does this, and the source field will be vanishing soon.Signed-off-by: David Brownell
Signed-off-by: Jean Delvare -
The i2c-ali1563 initialization looks quite broken to me:
* If the I/O space isn't enabled, we forcibly set 3 bits in
the PCI configuration space instead of just the one enabling
the I/O space.
* After that we pretend to check if the write worked, but we
don't actually read the new value from the register.
* It's probably not a good idea to enable the I/O space if no
base address has been set.So I propose the following changes to that part of the driver:
* Merge ali1563_enable() into ali1563_setup().
* Check the base address before the I/O space enabled bit.Signed-off-by: Jean Delvare

This reverts some bogosity from the dynamic command-line
changes made on sparc32 and sparc64.Drivers such as drivers/sbus/char/openprom.c reference
saved_command_line, and can be modular.The boot_command_line is __initdata, yet the dynamic command-line
changes add modular exports of that symbol, obviously wrong.Signed-off-by: David S. Miller

NF_CT_STAT_INC assumes rcu_read_lock in nf_hook_slow disables
preemption as well, making it legal to use __get_cpu_var without
disabling preemption manually. The assumption is not correct anymore
with preemptable RCU, additionally we need to protect against softirqs
when not holding nf_conntrack_lock.Add NF_CT_STAT_INC_ATOMIC macro, which disables local softirqs,
and use where necessary.Signed-off-by: Patrick McHardy
